Interactionist and Input Theories of Second Language Acquisition

Interactionist and Input Theories of Second Language Acquisition

This paper discusses social interaction theory and the interaction hypothesis and how they deal with the significance of interaction in a learning environment which contrasts with the nativist theories of language acquisition like the input hypothesis espoused by Krashen. According to interaction theorists such as Long and Vygotsky, environmental factors play a critical role in second language acquisition.
